This patch (as1654) fixes a very old bug in ehci-hcd, connected with
scheduling of periodic split transfers. The calculations for
full/low-speed bus usage are all carried out after the correction for
bit-stuffing has been applied, but the values in the max_tt_usecs
array assume it hasn't been. The array should allow for allocation of
up to 90% of the bus capacity, which is 900 us, not 780 us.
The symptom caused by this bug is that any isochronous transfer to a
full-speed device with a maxpacket size larger than about 980 bytes is
always rejected with a -ENOSPC error.

This patch (as1653) fixes a bug in ehci-hcd. Unlike iTD entries, an
siTD entry in the periodic schedule may not complete until the frame
after the one it belongs to. Consequently, when scanning the periodic
schedule it is necessary to start with the frame _preceding_ the one
where the previous scan ended.
Not doing this properly can result in memory leaks and failures to
complete isochronous URBs.

This patch (as1652) fixes a long-standing bug in ehci-hcd. The driver
relies on status polls to know when to stop port-resume signalling.
It uses the root-hub status timer to schedule these status polls. But
when the driver for the root hub is resumed, the timer is rescheduled
to go off immediately -- before the port is ready. When this happens
the timer does not get re-enabled, which prevents the port resume from
finishing until some other event occurs.
The symptom is that when a new device is plugged in, it doesn't get
recognized or enumerated until lsusb is run or something else happens.
The solution is to re-enable the root-hub status timer after every
status poll while a port resume is in progress.
This bug hasn't surfaced before now because we never used to try to
suspend the root hub in the middle of a port resume (except by
coincidence).

This patch (as1649) adds a mechanism for host controller drivers to
inform usbcore when they have begun or ended resume signalling on a
particular root-hub port. The core will then make sure that the root
hub does not get runtime-suspended while the port resume is going on.
Since commit 596d789a211d134dc5f94d1e5957248c204ef850 (USB: set hub's
default autosuspend delay as 0), the system tries to suspend hubs
whenever they aren't in use. While a root-hub port is being resumed,
the root hub does not appear to be in use. Attempted runtime suspends
fail because of the ongoing port resume, but the PM core just keeps on
trying over and over again. We want to prevent this wasteful effort.

This patch (as1648) fixes a regression affecting nVidia EHCI
controllers. Evidently they don't like to have more than one async QH
unlinked at a time. I can't imagine how they manage to mess it up,
but at least one of them does.
The patch changes the async unlink logic in two ways:
Each time an IAA cycle is started, only the first QH on the
async unlink list is handled (rather than all of them).
Async QHs do not all get unlinked as soon as they have been
empty for long enough. Instead, only the last one (i.e., the
one that has been on the schedule the longest) is unlinked,
and then only if no other unlinks are in progress at the time.
This means that when multiple QHs are empty, they won't be unlinked as
quickly as before. That's okay; it won't affect correct operation of
the driver or add an excessive load. Multiple unlinks tend to be
relatively rare in any case.

This patch (as1647) attempts to work around a problem that seems to
affect some nVidia EHCI controllers. They sometimes take a very long
time to turn off their async or periodic schedules. I don't know if
this is a result of other problems, but in any case it seems wise not
to depend on schedule enables or disables taking effect in any
specific length of time.
The patch removes the existing 20-ms timeout for enabling and
disabling the schedules. The driver will now continue to poll the
schedule state at 1-ms intervals until the controller finally decides
to obey the most recent command issued by the driver. Just in case
this hides a problem, a debugging message will be logged if the
controller takes longer than 20 polls.
I don't know if this will actually fix anything, but it can't hurt.

USB/xhci: Misc fixes for 3.8.
Hi Greg,
Here's six patches for xHCI and the USB core. There's a couple of
patches to fix xHCI 1.0 field formats, some memory leaks, dead ports,
and USB 3.0 remote wakeup disabling.
All of these are marked for stable.
I know I owe you some re-works of failed stable patches from my last
patchset round, but I don't think I'm going to get to them before I head
off to Linux Conf Australia tomorrow.

Usb3.0 device defines function remote wakeup which is only for interface

To calculate the TD size for a particular TRB in an isoc TD, we need
know the endpoint's max packet size. Isochronous endpoints also encode
the number of additional service opportunities in their wMaxPacketSize
field. The TD size calculation did not mask off those bits before using
the field. This resulted in incorrect TD size information for
isochronous TRBs when an URB frame buffer crossed a 64KB boundary.
For example:
- an isoc endpoint has 2 additional service opportunites and
a max packet size of 1020 bytes
- a frame transfer buffer contains 3060 bytes
- one frame buffer crosses a 64KB boundary, and must be split into
one 1276 byte TRB, and one 1784 byte TRB.
The TD size is is the number of packets that remain to be transferred
for a TD after processing all the max packet sized packets in the
current TRB and all previous TRBs.
For this TD, the number of packets to be transferred is (3060 / 1020),
or 3. The first TRB contains 1276 bytes, which means it contains one
full packet, and a 256 byte remainder. After processing all the max
packet-sized packets in the first TRB, the host will have 2 packets left
to transfer.
The old code would calculate the TD size for the first TRB as:
total packet count = DIV_ROUND_UP (TD length / endpoint wMaxPacketSize)
total packet count - (first TRB length / endpoint wMaxPacketSize)
The math should have been:
total packet count = DIV_ROUND_UP (3060 / 1020) = 3
3 - (1276 / 1020) = 2
Since the old code didn't mask off the additional service interval bits
from the wMaxPacketSize field, the math ended up as
total packet count = DIV_ROUND_UP (3060 / 5116) = 1
1 - (1276 / 5116) = 1
Fix this by masking off the number of additional service opportunities
in the wMaxPacketSize field.
This patch should be backported to stable kernels as old as 3.0, that
contain the commit 4da6e6f247a2601ab9f1e63424e4d944ed4124f3 "xhci 1.0:

than 3.2 because of commit 29cc88979a8818cd8c5019426e945aed118b400e

An isochronous TD is comprised of one isochronous TRB chained to zero or
more normal TRBs. Only the isoc TRB has the TBC and TLBPC fields. The
normal TRBs must set those fields to zeroes. The code was setting the
TBC and TLBPC fields for both isoc and normal TRBs. Fix this.

btrfs_start_delalloc_inodes() locks the delalloc_inodes list, fetches the
first inode, unlocks the list, triggers btrfs_alloc_delalloc_work/
btrfs_queue_worker for this inode, and then it locks the list, checks the
head of the list again. But because we don't delete the first inode that it
deals with before, it will fetch the same inode. As a result, this function
allocates a huge amount of btrfs_delalloc_work structures, and OOM happens.

First, though the current transaction->aborted check can stop the commit early
and avoid unnecessary operations, it is too early, and some transaction handles
don't end, those handles may set transaction->aborted after the check.
Second, when we commit the transaction, we will wake up some worker threads to
flush the space cache and inode cache. Those threads also allocate some transaction
handles and may set transaction->aborted if some serious error happens.
So we need more check for ->aborted when committing the transaction. Fix it.

I noticed a WARN_ON going off when adding csums because we were going over
the amount of csum bytes that should have been allowed for an ordered
extent. This is a leftover from when we used to hold the csums privately
for direct io, but now we use the normal ordered sum stuff so we need to
make sure and check if we've moved on to another extent so that the csums
are added to the right extent. Without this we could end up with csums for
bytenrs that don't have extents to cover them yet. Thanks,

A user reported a BUG_ON(ret) that occured during tree log replay. Ret was
-EAGAIN, so what I think happened is that we removed an extent that covered
a bitmap entry and an extent entry. We remove the part from the bitmap and
return -EAGAIN and then search for the next piece we want to remove, which
happens to be an entire extent entry, so we just free the sucker and return.
The problem is ret is still set to -EAGAIN so we trip the BUG_ON(). The
user used btrfs-zero-log so I'm not 100% sure this is what happened so I've
added a WARN_ON() to catch the other possibility. Thanks,

We drop the extent map tree lock while we're logging extents, so somebody
could come in and merge another extent into this one and screw up our
logging, or they could even remove us from the list which would keep us from
logging the extent or freeing our ref on it, so we need to make sure to not
clear LOGGING until after the extent is logged, and then we can merge it to
adjacent extents. Thanks,

The vexpress-sysreg driver does not have to be initialized
early, when the platform doesn't require this. Unfortunately
in such case it wasn't initialized correctly - master site
lookup and config bridge registration were missing. Fixed now.

As the kernel is able to cope with multiple clusters,
uncomment the A7 cores in the Device Tree for V2P-CA15_A7
tile, making all 5 cores available to the user.

In ARM multi-cluster systems the MPIDR affinity level 0 cannot be used as a
single cpu identifier, affinity levels 1 and 2 must be taken into account as
well.
This patch extends the MPIDR usage to affinity levels 1 and 2 in versatile
secondary cores start up code in order to compare the passed pen_release
value with the full-blown affinity mask.
